Hello,

I am trying to verify my concentration gradient along my crevice by plotting the electroneutrality (EN) of the species versus the crevice position.

However, I cannot find a place to add the equation for EN manually and then generate a 1D plot. Does anyone have any suggestions? I cannot even find a tutorial video that will help.

Thanks, Lins

Hi

Are you using Nernst-Planck physics? In that one of the species is bound via the electroneutrality condition, i.e. it is not calculated at all. Of course you can make a Line Graph and plot the sum z_i*c_i along any line you define. You may either define the sum as a variable of its own or just write it in the variable definition box.
